Rick Ross just got out-bawsed ... but he ain't sweatin' it -- 'cause even though he got CRUSHED in a celeb hoops game ... he raised a TON of cash for a local charity.
Ross stepped up to coach a team in the 4th annual Nike South Beach Celebrity Court of Dreams game this past weekend to benefit the South Beach Charitable Foundation for kids.
The hip-hop star coached a team of celebs -- including NFL players Antrel Rolle and the Pouncey twins ... in an effort to beat the "South Beach All-Stars," coached by ex-NFL lineman Bryant McKinnie.
In the end ... Ross' squad just couldn't hang and they lost to Bryant's team 62-38.
But the event raised $35,000 for charity -- so, hard to call anyone a loser after that.
